Summary

The Pegatron `Tdelo64.sys` driver exposes a privileged device interface `\\.\TdeIo` that fails to restrict access to sensitive IOCTL functionality. Lack of privilege validation and kernel memory address verification allows a local attacker to perform arbitrary kernel memory read and write operations.

Risk Assessment

An attacker can escalate privileges to `NT AUTHORITY\SYSTEM`, bypass security products, steal credentials, or fully compromise the system, posing a critical risk to data confidentiality and integrity.

Recommendation

Immediately update the `Tdelo64.sys` driver to the latest version provided by Pegatron. If no update is available, temporarily block access to the `\\.\TdeIo` interface using security policies.

Original NVD description (English source)

Pegatron `Tdelo64.sys` exposes a privileged device interface, `\\.\TdeIo`, that fails to properly restrict access to sensitive IOCTL functionality. The driver's IOCTL dispatcher does not validate caller privileges or verify user-supplied kernel memory addresses before performing memory operations. By sending crafted requests to IOCTL, a local attacker can achieve arbitrary kernel memory read and write operations, leading to privilege escalation to `NT AUTHORITY\SYSTEM`, security product bypass, credential theft, or complete system compromise.
